NAME

       zmore - file perusal filter for crt viewing of compressed text

SYNOPSIS

       zmore [ name ...  ]

DESCRIPTION

       Zmore  is a filter which allows examination of compressed or plain text
       files one screenful at a time on a soft-copy terminal.  zmore works  on
       files  compressed with compress, pack or gzip, and also on uncompressed
       files.  If a file does not exist, zmore looks for a file  of  the  same
       name with the addition of a .gz, .z or .Z suffix.

       Zmore  normally  pauses  after each screenful, printing --More-- at the
       bottom of the screen.  If the user then types a  carriage  return,  one
       more line is displayed.  If the user hits a space, another screenful is
       displayed.  Other possibilities are enumerated later.

       Zmore looks in the file /etc/termcap to determine terminal characteris-
       tics,  and to determine the default window size.  On a terminal capable
       of displaying 24 lines, the default window size is 22 lines.  To use  a
       pager other than the default

       Other  sequences  which  may  be  typed  when  zmore  pauses, and their
       effects, are as follows (i is an optional integer argument,  defaulting
       to 1) :

       i<space>
              display  i  more  lines, (or another screenful if no argument is
              given)

       ^D     display 11 more lines (a ``scroll'').  If i is given,  then  the
              scroll size is set to i.

       d      same as ^D (control-D)

       iz     same  as  typing  a space except that i, if present, becomes the
              new window size.  Note that the window size reverts back to  the
              default at the end of the current file.

       is     skip i lines and print a screenful of lines

       if     skip i screenfuls and print a screenful of lines

       q or Q quit reading the current file; go on to the next (if any)

       e or q When  the prompt --More--(Next file: file) is printed, this com-
              mand causes zmore to exit.

       s      When the prompt --More--(Next file: file) is printed, this  com-
              mand causes zmore to skip the next file and continue.

       =      Display the current line number.

       i/expr search  for  the i-th occurrence of the regular expression expr.
              If the pattern is not found, zmore goes on to the next file  (if
              any).   Otherwise,  a screenful is displayed, starting two lines
              before the place where the expression  was  found.   The  user's
              erase  and  kill  characters  may  be  used  to edit the regular
              expression.  Erasing back past  the  first  column  cancels  the
              search command.

       in     search  for  the  i-th occurrence of the last regular expression
              entered.

       !command
              invoke a shell with command.  The character `!' in "command"  is
              replaced  with the previous shell command.  The sequence "\!" is
              replaced by "!".

       :q or :Q
              quit reading the current file; go on to the next (if any)  (same
              as q or Q).

       .      (dot) repeat the previous command.

       The commands take effect immediately, i.e., it is not necessary to type
       a carriage return.  Up to the time when the command character itself is
       given, the user may hit the line kill character to cancel the numerical
       argument being formed.  In addition, the user may hit the erase charac-
       ter to redisplay the --More-- message.

       At any time when output is being sent to the terminal, the user can hit
       the quit key (normally control-\).  Zmore will stop sending output, and
       will display the usual --More-- prompt.  The user may then enter one of
       the above commands in the normal manner.  Unfortunately, some output is
       lost  when this is done, due to the fact that any characters waiting in
       the terminal's output queue are flushed when the quit signal occurs.

       The terminal is set to noecho mode by this program so that  the  output
       can  be continuous.  What you type will thus not show on your terminal,
       except for the / and !  commands.

       If the standard output is not a teletype, then  zmore  acts  just  like
       zcat, except that a header is printed before each file.
